プテロスチルベンの10大メリット＋リスク、投与量、B2Bサプライヤーガイド

When it comes to trending nutraceutical ingredients, pterostilbene has been catching the eye of researchers, formulators, and manufacturers worldwide. Often compared to レスベラトロール, pterostilbene is a naturally occurring compound found in blueberries, grapes, and some heartwood trees. Its growing popularity comes from its potential health benefits, superior bioavailability compared to resveratrol, and wide application across industries like cosmetics, dietary supplements, functional foods, beverages, health products, and pharmaceuticals.

But before you decide whether to use it in your next product formulation, it’s important to understand what pterostilbene does, its potential risks, and where to source it from a trusted 製造業者および輸出業者.

What is Pterostilbene?

Pterostilbene is a stilbene compound structurally similar to resveratrol but with two methoxy groups, which make it more lipophilic and longer-lasting in the body. This improved stability and absorption means pterostilbene often provides stronger effects at lower doses compared to resveratrol.

It is available in bulk powder そして capsule/tablet-ready supplement form, often marketed as trans-pterostilbene or branded as Silbinol®.

Top Benefits of Pterostilbene

1. Antioxidant Protection

Like resveratrol, pterostilbene is a potent antioxidant. It helps neutralize free radicals, reducing oxidative stress linked to aging, inflammation, and chronic disease.

2. Brain Health & Cognitive Function

Early research suggests pterostilbene may support memory, learning, and neuroprotection by crossing the blood-brain barrier more effectively than resveratrol. This makes it attractive for anti-aging supplements and nootropic formulations.

3. Heart & Metabolic Support

Pterostilbene may help regulate blood sugar, support cholesterol balance, and improve vascular function—making it an ingredient of interest in cardiovascular supplements and healthy aging products.

4. Anti-Inflammatory Properties

Studies point to its ability to downregulate inflammatory pathways, potentially supporting joint health, immune balance, and recovery.

5. Longevity & Anti-Aging

Because of its sirtuin-activating effects (similar to resveratrol), pterostilbene is explored in the context of lifespan extension and healthy aging.

6. Skin Benefits

で cosmetic applications, pterostilbene may protect against UV damage, oxidative stress, and collagen breakdown, making it a promising anti-aging skincare ingredient.

7. Weight Management Support

Animal studies suggest pterostilbene may improve lipid metabolism and fat oxidation, giving it potential value in weight management supplements.

8. Synergy with NMN & Quercetin

When combined with NMN (nicotinamide mononucleotide) または ケルセチン, pterostilbene may enhance NAD+ metabolism, cellular energy, and antioxidant defenses.

9. Natural Food & Beverage Additive

Beyond supplements, pterostilbene is being studied for functional beverages and health foods, where its stability provides advantages over resveratrol.

10. Pharmaceutical Potential

Ongoing research is exploring pterostilbene’s role in neurology, oncology, and metabolic disorders, making it an ingredient of long-term interest for pharmaceutical developers.

Pterostilbene vs Resveratrol: Which is Better?

レスベラトロール: Widely studied, affordable, but low bioavailability.
プテロスチルベン: Higher absorption, longer half-life, requires smaller doses.

For B2B buyers, pterostilbene is often seen as the premium alternative to resveratrol, especially in products positioned for longevity, brain health, and advanced anti-aging.

Uses of Pterostilbene in Different Industries

化粧品とスキンケア: Anti-aging creams, serums, and UV-protection formulations.
栄養補助食品: Capsules, tablets, or blended formulas with NMN, quercetin, or resveratrol.
食品・飲料: Functional drinks, powders, and fortified snacks.
Health & Wellness Products: Longevity, brain health, and immune support blends.
医薬品研究: Neuroprotection, anti-inflammatory, and metabolic health applications.

Pterostilbene Dosage & Forms

Common supplement dose: 50–150 mg/day.
Bulk powder: Suitable for formulation and custom blends.
Trans-pterostilbene tablets/capsules: Branded forms like Silbinol®.

Always consult regulatory guidelines for dosage limits in different markets.

Pterostilbene Side Effects & Safety

For most people, pterostilbene is considered safe at standard supplemental doses. Reported side effects are mild but may include:

Slight increases in LDL cholesterol (dose-dependent)
Headache or dizziness (rare, usually at high doses)
Unknown safety in pregnancy or lactation

Compared to resveratrol, pterostilbene has fewer gastrointestinal issues and better tolerance.

Should You Choose Pterostilbene or Resveratrol?

If your goal is cost-effective antioxidant support, resveratrol may be enough. But if your market demands premium, higher-absorption ingredients, pterostilbene is the smarter choice. Many brands now use both together to create synergistic longevity and brain health products.
